Thank you for viewing. I purchased this new on Rakuten and used it for 3-4 months. I am selling it because the shape of the key changed at my new home. This is a set of the SwitchBot smart lock and fingerprint authentication keypad touch. I installed it because I was worried about my child losing their keys. By connecting it to the hub, I can check notifications and history of my child's return even while I'm at work. - Brand: SwitchBot - Color: Black Included items ・Card key ・Fingerprint authentication pad ・Main unit 【Notes】 ・Please refrain from purchasing if you are sensitive to used items. ・Please check the photos for the included items. ・Adhesive tape for the fingerprint authentication pad and new batteries are not included.
